Due to the special role of hooks in lifting machinery and the heavy load they need to bear, the specific technical requirements for the production and application of hooks in modern industrial applications are as follows:

Hook products should have a certificate of conformity from the manufacturer when they leave the factory. Hooks used in important departments such as the transportation industry must undergo flaw detection inspections. Defects in the hook must not be repaired by welding, and the surface of the hook must not have defects such as cracks, folds, or overburning. The surface roughness of the hook should not be too large. The forging material of the hook is generally forged from high-quality carbon steel or other special materials. Hooks that have been subjected to overload tests should be scrapped.

Since hooks are used for lifting heavy objects and are highly dangerous, and the items they carry may be fragile and fall, modern industrial applications have high requirements for the quality and safety of hooks. Hooks must undergo the following safety inspections. Hooks driven by manual operation are generally tested with 1.2 times the rated load as the test load; hooks of the lifting mechanism are tested with 2 times the rated load. Hooks that pass the inspection should be marked in the low-stress area of the hook, including rated lifting capacity, inspection mark, production number, etc.
